Video surveillance, when the car is off
Does anyone have any ideas on how to implement video surveillance when the car is off.
Lets say we have a fully functioning CarPC with capture card, cameras and sofware installed. Also, wireless card might be used to transfer data to home or office. (ad-hoc)
Any ideas how to power the unit?
2nd Battery + a switch or some capacitors?
dual boot with linux just for video capture?
But, I'm interested more in how to wire everything....
Are there any intellingent power supplies that would work ? ACPI..
